Application filed April 28, 1914, Serial No. 834,899. Renewed December17, 1918. Serial No. 267,213.

To all whom it may concern:

Be it known that I, An'ruun E. RIDHOUT, a citizen of the United States,and a resident of Chicago, in Cook county, State of Illinois, haveinvented an Improvement in Strip-Serving Devices, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

The,present invention relates to an improvement in strip servingdevices, the object being to provide an apparatus in which the strip, tobe used subsequently for sealing packages or the like, may be heldstationary while it is being moistened or otherwise rendered adhesive.

In the drawings which form a part of this specification and in which Ihave illustrated a single embodiment of my invention,

Fig. 5 is a side elevation of part of the carriage showing the relativepositions of the parts when the carriage is moving away from the tapesupply.

It will be understood that the drawings submitted herewith are forillustrative pur poses only, and are intended to represent but oneembodiment of a strip serving device made in accordance with myinvention. This particular form of machine, according to Fig. 1,comprises a holder 1, for a supply of tape, a fixed platen 2, a carriagemember arranged to move alternately toward and away from the tapesupplyand hereinafter referred to as an oscillating carriage which is adaptedto carry means 3 for rendering adhesive, strips of tape either gummed orungummed, suitable ways 4 for the said carriage, and tape severingmeans. In the present case, the device illustrated is adapted to carry asupplv of gummed tape, strips of which are drawn out and moistened bymeans of apparatus more particularly described below. The platen 2,which is shown asloca-ted adjacent to the tape holder 1 and above thestrip moistening means, is rigidly mounted so that, after a strip oftape 9 has been drawn from the supply, it may be pressed between thisunyielding platen and the moistenine' apparatus to more effectuallyimpregnate the lue on the tape with the moistenin fluid.

The osclllating carriage referred to above, and shown in detail in Fig.2 of the'drawings, comprises a frame portion 5 supported upon rotaryhearings or wheels 6 which run upon suitably shaped ways or tracks 4.Mounted upon this oscillating carriage, I have provided mechanismadapted to grip the free end of the tape when the carriage .reaches thatend of its course adjacent to the tape supply. Upon its direction beingreverse, a strip is drawn out a sufficient distance to expose thedesired length of tape, whereupon the tape end is automatically releasedand the strip drawn out is in position to be moistened. As shown inFigs. 2 and 3, the tape gripping means comprises in part a fixedtransverse bar 7 suitably mounted on the frame work 5 of the oscillatingcarriage to engage the free end of the tape. Adjacent thereto is anothersimilar but movable bar 8 adapted to be held in spring pressedengagement therewith thus securely gripping the tape between them. Inorder that this bar 8 may be raised and lowered alternately to grip andrelease-the tape strip, it is mounted upon a pair of slidable supports10 adapted to slide in bearings 11 positioned at both sides of thecarriage and forming a part of the frame work thereof. To hold thetransverse bars out of engagement with each other, these supports areprovided at their lower ends with latches 12 adapted to engage the endof spring pressed bolts 13 when the carriage reaches the end of itsstrip drawing oscillation, and to be disengaged therefrom when thecarriage returns to its position adjacent. to the tape supply. For thispurpose the bolts 13, mounted in suitable bearings 14 at each side ofthe carriage, are provided with projecting lugs 15 adapted to engagecorresponding adjustable stops 16 (Fig. 1) to disengage the latch 12.The slidable supports also have projecting lugs 17 which engagecorresponding adjustable cam shapedstops 18 positioned at the oppositeend of the machine from that carrying the stops 16 and adapted todepress the slidaible supports so that the latches 12 may reengage thebolts13 thus separating the transverse the roller 21 journaled on amovable arm 22 also mounted on the tape support and adapted to yieldagainst spring pressure when the oscillating carriage bears aga nst 1tat the end of its moistening oscillation.

While the strip is being drawn out, the parts mounted upon the carriageoccupy the relative positions shown n Fig. 5 of the drawings. Referringto this figure, the moistening roller 3 is suitably ournaled 1n theframe work of the oscillating carriage to rotate in a supply of Water,or in a supply of some adhesive material, in case the machine is to beoperated with ungummed tape. When the carriage reaches the end of lts-3'5-.oscillation away from the tape supply,

marked "in the present instance, by a pair of stops 18 and 23 (Fig. 1)the movabletape gripping bar 8 is pressed down .to release the tape inthe manner heretofore described, and the moistening roller 3 issimultaneously released to engage the tape, these parts now occupyingthe relative positions shown in Fig. 2 of the drawings. The mechanismcontrolling the operation of the moistening roller comprises lugs 24,shown in the present case as projecting from extensions 24 of the shaftof the moistening roller, and latches 25 pivoted at 26 on opposite sidesof the frame 5 of the carriage and adapted to be held in spring pressedengagement with the lugs 24 when the parts are'in the position shown inFig. 5. To effect this engagement, the extensions 24 are positioned toengage adjustable cam shaped stops 27 (Fig. 1) similar to the stops 18described in connectionwith the tape gripping mechanism, but positionedto operate at the end of the motion of the' carriage toward the tapesupply. Upon contact with these cam shaped stops 27, the extensions 24are pressed downwardly against pressure of'the springs 28, and thelatches 25 are forced into engagement with the said lugs 24, as shown inFig. 5 of the drawings, by-pressure of a spring 29, thus holding themoistening roller down and out of contact with the platen. Reversin theoperation, in order to disengage the latches 25 from the lugs 24, stops23 are provided, suitably mounted on ways 30 forming a part of the framework of the machine so that the stops may be moved back and forth toaccommodate different lengths of tape. The latches 25 are also providedwith projecting lugs 31 adapted to engage the stops 23 just mentionedand which press the latches out of engagement with the lugs 24, thusreleasing the moistener. When disengaged in this manner, the moisteneris pressed upwardly against the unyielding platen with sufficientpressure from the spring 28 upon the tape strip during the moist'eningoperation to thoroughly incorporate the gum and water.

When the carriage is in motion toward the tape supply, the strip of tapeis not only moistened, but it is also severed by means of 4 a cuttingmechanism which cooperates with the carriage. Fig. 1 indicates thearrangement of the cutting mechanism relative to the entire apparatus.Referring now to Fig. 4, which shows the cutting mechanism in detail,the latter comprises a fixed blade 32 suitably mounted adjacent to oneend of the platen, a cooperating movable blade 33 piv oted so as toswing across the path of the strip of tape to sever it from the supply,and suitable means for actuating the movable blade. This movable bladeis provided with a projecting lug 34 and a spring 35 adapted to hold itnormally out of operative position with respect to the fixed blade.Referring again to Fig. 1, where mechanism for actuating the movableblade is shown in connection with the oscillating carriage, a lever 36is pivoted in the fixed framework of the apparatus so that its free endnormally rests in the path of a trip member 37 mounted on the frame ofthe. oscillating carriage and adapted to yield when the carriage movesaway from the tape supply and to remain rigid during the return motion.At the opposite end of the lever 36 is pivoted -one end of a connectingrod 38, the other end of which is similarly connected to a second lever39 pivoted to the frame work of the machine in a position adjacent tothe tape support. The free end 40 of this last mentioned lever 39 formsa cam shaped portion adapted to engage a toggle 41 shown in detail inFig. 4. This toggle 41 is adapted to 'be moved vertically in guides 42also attached to the fixed frame work of the ma chine. At the upper endof the toggle, there is a pro ecting arm 43'adap-ted to engage the lugs34 heretofore described as projecting from the movable blade 33. It willbe understood that when the carriage moves away from the tape supply,the trip 37, so pivoted on the carriage as to yield in one direction andto remain rigid in the opposite direction, yields suflicient-ly to passover the free end of the lever 36, here shown as cam shaped. When thecarriage is reversed, however, the trip 37 now rigid, contacts with thefree end of the lever, tilting the same forward sharply thus actuatingthe companion lever 39 through the connecting rod 38 and efi'ecting amovement of the movable blade 33 by a thrust of the toggle and itsprojecting arm. In connection with the said toggle 41 I have provided aspring 44 designed to accelerate the return movement of the toggle afterit has actuated the movable blade.

It will be understood that the carriage member herein referred to may becaused to oscillate by any suitable means; but I have shown for thispurpose mechanism whereby the said carriage member may be moved back andforth by hand power. This mechanism comprises a handled lever 45(Fig. 1) having one end pivoted at 46, and provided with a longitudinalslot 47. A pin 48 pro jecting from the movable carriage engages the saidlongitudinal slot so that when the lever arm is moved back and forth,the sides of the slot bear against the pin 48 thus moving the carriagein the direction of motion of the lever. The carriage is furtherprovided with a roller 49 suitably journaled in the frame thereof adacent to the gripping mechanism heretofore described, its function beingto press the tape strip constantly against the platen. This roller has apluraL' ity of projecting peripheral flanges 50 held normally in springpressed engagement with the platen and the gummed side of the tape bymeans of springs 51 positioned to press upwardly against the shaft 52 ofthe said roller, the purpose of the flanges being to afford a minimum ofsurface so that the gum will not adhere thereto in such quantity as tohinder eflieient operationof the device.

In operation, the free end of the tape is brought down under the roller20 and over the roller 21, extending somewhat beyond the latter. Theoscillating carriage is then advanced toward this free end, the partsbeing in the position shown in Fig. 2. The tape end runs between thefixed bar 7 and the movable bar 8 until continued movement of thecarriage brings the lugs 15 on the bolt 13 into contact with the stop16, whereupon the gripping mechanism is pressed into operation andseizes the tape. Simultaneously the'rewith, the cam stops 27 engage thelugs 24 of the moistening roller 3 and the latter is pressed down out ofcontact with the platen, in which position it is held by means of thespring pressed latch 25. By swinging the operating lever away from thetape I supply, the carriage is caused to move in the same direction,drawing with it the strip of tape 9 (Fig. 5) held securely b thegripping means in the manner hereto ore described. The stops 23 and thecam stops 18 are adthe moistening of the tape but also causing the stripto be severed in the manner likewise previously described in detail.From the foregoing description and method of operation, it will beobvious that a machine of thekind under consideration may be operatedwith considerable rapidity to serve strips of adhesive tape in definitelengths and in proper condition for being applied to boxes, packages, orother articles to be sealed.

My invention is not limited to the specific form shown in the drawingsand described at length in the specification.
